05E High Battery Voltage
If “Yes” is displayed, the DC battery voltage has increased above the
value set in the 11A High Battery Cut Out VDC menu item.
This can be caused by a solar array or other charging source not being
regulated. Check the operational status of all the DC controllers in the
system.
If NiCad batteries are used, it might be necessary to increase the value in
the 11A High Battery Cut Out VDC menu item.
The inverter automatically resets once the battery voltage decreases to
3 volts for 24-volt models, or 6 volts 48-volt models, below the HBCO
setting.
AC current is still passed-through to the load if the AC source is within
acceptable tolerances.
05F External Err (Stacked)
If “Yes” is displayed, then the inverter showing the error (Inverter 1) has
received a shutdown command from the stacked inverter (Inverter 2).
Check the stacked inverter (Inverter 2) for error conditions and clear the
error condition.
After the error condition is resolved, on the primary inverter (Inverter 1),
go to 01A Inverter and turn the inverter OFF, then back ON to clear this
error message.
05G Input Relay Failure
If “Yes” is displayed, an internal AC transfer relay (AC1 or AC2) has
failed. This condition maybe caused by an AC backfeed (AC plugged into
the inverter’s output) or a welded relay condition.
05E High Battery
Voltage YES
05F External Err
(Stacked) YES
Note:
The External Error condition will shut down both inverters.
05G Input Relay
Failure YES
Note:
This condition will shut down the inverter.
